🚀 WIZnet Launches W6300: High-Speed Ethernet in a Compact Form

 

We are excited to announce the official release of the W6300, WIZnet’s newest iEthernet chip that brings together high-speed performance, hardware TCP/IP offloading, and compact form factor—all optimized for today’s demanding embedded applications.

The W6300 is engineered to deliver up to 90 Mbps throughput via a high-speed QSPI interface, making it the fastest SPI-compatible chip in the WIZnet portfolio to date.

⚡ Up to 80 Mbps over QSPI — Ethernet Without the Bottlenecks

The W6300 sets a new benchmark in SPI-based Ethernet chips. By leveraging a Quad SPI interface, it achieves data transfer rates over 80 Mbps, allowing developers to design Ethernet-enabled systems with the speed of traditional parallel interfaces—without the complexity.

This makes the W6300 ideal for applications that require:

• High-throughput data logging

• Low-latency control systems

• Multimedia and real-time streaming

• Secure, stable networking in compact embedded devices

🔁 The W5300 Legacy, Reinvented

WIZnet’s W5300 chip has long been known for its high-performance capabilities, with an 8/16-bit parallel bus interface and robust TCP/IP hardware stack. However, the W5300 comes in a large 100-pin LQFP package, limiting its use in compact designs and requiring more complex PCB routing.

With the W6300, we’ve redefined performance for modern embedded systems:

Feature	W5300	W6300
Interface	8/16-bit Parallel Bus	High-Speed QSPI (80 MHz)
Max Throughput	Up to 80 Mbps	Up to 90 Mbps
Package	100LQFP	Compact QFN48 / LQFP48
Socket Channels	8	8
Protocol Support	IPv4 only	IPv4 & IPv6

The W6300 brings similar high-performance networking in a smaller, easier-to-integrate form, using SPI instead of parallel bus for greater design flexibility—especially for MCUs and compact layouts.

🔑 Key Features of the W6300

• Hardware TCP/IP Stack
  Offloads TCP, UDP, IPv4, and IPv6 processing from the host MCU for deterministic Ethernet communication.

• QSPI Interface
  Enables high-throughput performance while reducing CPU load and simplifying hardware integration.

• 8 Independent Hardware Sockets
  Handle multiple connections simultaneously for advanced networking use cases.

• MACRAW Mode
  Offers direct access to Ethernet frames for protocol development or monitoring.

• Compact Package Options
  Available in QFN48 and LQFP48, suitable for small-form-factor products.

🛠 Ready for a New Generation of Products

The W6300 is ideal for:

• Industrial controllers and HMIs

• Smart IoT edge devices

• Surveillance and NVR systems

• Environmental monitoring and sensing nodes

• Secure gateway and communication modules

It provides developers with a balance of speed, scalability, and design simplicity, enabling modern Ethernet-enabled devices without the constraints of bulky packages or parallel bus complexity.
